Thin Walled Tube

The cold-formed thin-walled tube has been widely applied in high seismic fortification intensity region and post-seismic reconstruction area because of light quality, high strength and small deformation. But the connection mode and mechanical properties of beam-column connections still need further study. According to the "strong column and weak beam" seismic design principle and the thinking of control the position of plastic hinge, adding haunch slabs at the end of beam to reduce the number of repeated welding and avoid brittle fracture. Through the low cyclic loading experiment, four beam-column connections with welded haunch under different axial compression ratios have been studied, and connection’s hysteretic performance, energy-dissipating capacity, bearing capacity, rigidity and failure mode have been discussed. The result shows that: 1) the ultimate bearing capacity of connection with welded haunch is much great, and the energy dissipation capacity is very well, which can make this connection to absorb and consume great energy in earthquake. This connection can meet the need of seismic design very well. 2) The connection with welded haunch experiences much cycling time, has long yield platform after yield, has great cumulative energy-dissipating capacity and well ductility. 3) the final destruction of connection with welded haunch is caused by the beam’s local buckling. And the yield surface is almost located at the outside of connections. 4) The axial compression ratios has great effect on the hysteretic performance, bearing capacity and stiffness degradation for the connection with welded haunch.

Hysteretic Performance

Double L-stiffened plate or haunch is used to strengthen the connection to meet the requirement of the code for seismic design of buildings: The principle of strong connection-weak connected member. The two kinds of reinforced connections are simple and easy to construct. Using software ANSYS to research is done on the connection under the monotonic load and low-frequency cyclic load. The results show that: the reinforced connections have high bearing capacity, superior hysteretic performance, and very good ductility; when failure the deformation of the joint region becomes smaller, and the plastic hinge shifts away from the region so as to prevent the brittle failure of the region; the beam has a long yielding plateau, and the bearing capacity decreases not very much after the beam yielding.

This paper presents an experimental study to know the seismic behaviour of the reinforced gangue concrete (RGC) columns. Four specimens of the RGC columns under cycle loadings were tested. The failure models, hysteretic performance, degradation rules of strength and stiffness, ductility and energy dissipation capacity are described and evaluated. It was concluded that the strength and stiffness of the RGC columns were improved with the increasing of steel ratio, column cross-section dimension and concrete strength. The tested RGC columns exhibit excellent seismic performance. The RGC columns have excellent ductility and can satisfy the request of the structural seismic design, thus they can be effectively used in RC structures.

Experimental study was performed on the hysteretic performance of H-beam to square tubular column connection with diaphragm-through. The main study parameters are the diaphragm thickness and planar dimension. The experiment shows that the bearing capacity and ductility of the connection are sufficient and the strength degradation is stable as well as the stiffness degradation. This kind of connection meets the requirements specified by current seismic design codes.
